      abstract     = {Context. Several new phenomena have arisen in the area of
                      study of the repeating thermonuclear explosions called
                      novae. For example, recurrent novae have been proven to be
                      efficient cosmic ray hadronic accelerators thanks to the
                      recent observations of RS Ophiuchi by different γ-ray
                      instruments. Novae have also been demonstrated to have the
                      ability to carve large cavities into the interstellar medium
                      (ISM), with parallels with the remnants of supernovae.Aims.
                      Our aims are to calculate the effects of novae on their
                      surrounding media, and the distances over which these
                      effects dominate over the average quantities that are
                      measured in the ISM.Methods. We calculated the filling
                      factor of novae and their contribution to cosmic ray fluxes
                      using cosmic ray propagation codes. To limit the atomic
                      density of the ISM surrounding the region of RS Oph, we used
                      Fermi-LAT observations of the region.Results. The filling
                      factor of novae in the Galaxy is not significant under all
                      assumptions done in the paper. They do not dominate over the
                      local cosmic ray fluxes, even at the lowest energies, for
                      distances larger than a few parsecs. The particle density of
                      the ISM surrounding them is, however, very much modified,
                      being lowered by more than one order of magnitude with
                      respect to galactic averages, confirming estimates done
                      using other observatories.Conclusions. Even though at global
                      galactic distances, novae do not seem to be dominating
                      cosmic ray transport, they have the power to modify the
                      conditions of their surrounding ISM over parsec distances.},
